x(x-y)2-(y-x)3
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
因式分解x(x+y)(x-y)-x(x+y)^2
化简 3x(x^2-x-1)-(x+1)(3x^-x) X^3(x-y)+x(y-x)
因式分解3x^2(x-y)+6x(y-x)
3^x+2x=y,x
计算:x+2y/x-y+2x/y-x-3y/x-y
化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方
[(3x+y)(x-y)-(2x+3y)(x-y)]*(x-y)
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
x^2(x-y)+(y-x)
2X(2X-3Y)-3Y(X+Y)
(-2x y)^2-(3y-x)(-x-3y)
